Abstract
A method and system for determining energy efficient routes is described. Map data represents road segments. Energy consumption data is obtained while a vehicle travels on a first road segment. Energy consumption data associated with the first road segment can be used to predict the expected energy consumption when traveling on a second road segment that has similar physical attributes to those of the first road segment. The predicted energy consumption data may be used to determine whether the second road segment is part of a most energy efficient route.
Claims20
A computer-implemented method of determining an energy efficient route for traveling from an origin to a destination, comprising:
- receiving a request for a route from an origin location to a destination location on a road network;
- calculating a route from the origin location to the destination location using road segment data and energy consumption data, wherein calculating a route includes:
- determining whether energy consumption data is associated with road segment data for each evaluated road segment;
- if the road segment data for a first road segment is not associated with the energy consumption data, predicting energy consumption for traveling on the first road segment using energy consumption data for a second road segment;
- and
- determining the route having the lowest calculated energy consumption.
A system for determining an energy efficient route from an origin to a destination, comprising:
- a data storage device having map data, energy consumption data, and program instructions;
- and
- a processor operable to execute the program instructions to calculate an energy efficient route from an origin to a destination using the map data and the energy consumption data, wherein if a first road segment represented by the map data is not associated with energy consumption data, the processor predicts a first energy consumption value for the first road segment by using a second energy consumption value associated with a second road segment having similar physical characteristics.
A geographic database system for use in calculating energy efficient routes, comprising:
- a representation of a road network in a geographic region, wherein the road network representation includes road segment data defining physical properties of an associated road segment;
- and
- a representation of energy consumption associated with traveling on road segments, wherein if the energy consumption representation does not include data for a first road segment, the road network representation includes a pointer to a second road segment, wherein the second road segment has physical properties similar to the first road segment, and wherein the energy consumption representation includes data for the second road segment.
